OZONE MACHINE.

Application filed April 14, 1921.

Chicago, county of Cook, and State of Illi- 1101s, have invented certainnew and useful Improvements in Ozone Machines,- of which the followingis a specification, and which are illustrated in the accompanying drawins, forming a part thereof.

he invention relates to ozone machine elements which may be used singlyor in groups as is customary in devices of this class.- The objects ofthe invention are to secure a high degree of eiiiciency, simplicity ofconstruction and ease of assembling and disassembling the parts.

A preferred embodiment of the invention is shown in the accompanyingdrawings, in which- Fig. 1 is a side levation, partly in section, of theimproved element;

Fig. 2 is an end elevation, the open position of one of the clampingdevices being shown in dotted lines;

Fig. 3 is a detail longitudinal sectional view, and 1 4 is a transversesection on the line 4-4 of Fig. 1.

The improved element comprises a dielectrio 1( preferably of glasstaking the form of a cylinder which may be closed at one end, as 11, forthe purpose of preventing the circulation of dust laden air through it.The outer electrode 12 is formed of two sheets of metal 13, 14, eachbearing alarge number of contact points, as 15, shown as being stampedfrom the metal sheet. The metal sheets 13, 14, are bent tosemi-cylindrical form, the width of each being such that when the twoare applied to the dielectric with the contact points 15 bearingthereagainst, they form substantially a complete cylinder.

'The other electrode 16, is preferably formed of a metallic foil andapplied to the inner surface of the dielectric and is held in contacttherewith by expansive spring elements, one of which, 17, is shown as anexpansible metal band and the other, 18, 1s a helical coil of springwire which preferably forms a part of one of the circuit wires 19.

The parts which-have been described being assembled are seated in a pairof chalrs 20, 21, each having feet 22, 23, which may be secured to asuitable support by means of Specification of Letters Patent.

screws. A curved clamping bar 24 is pivoted, as shown at 25, to one ofthe side arms of each of the chairs and may be closed down over theelectrode 12. The free end of th bar 24 is provided with a hook 26 forengagement by a latch 27 carried by a hasp 28 pivotally attached, at 29,to the other arm of the chair.

The contacts 15 are of uniform len th so that all of them rest upon thedie ectric when the parts are assembled. One of the circult wires 30 mayconveniently be' connected with the electrode 12 through one of thechairs, as 20, and is shown as secured thereto by one of the securingscrews 31.

In use a high potential current being passed through the circuit, an arcis developed between each of the contacts 15 and the electrode 16causing the generation of ozone in a well known manner.

In devices of this general character, there being a circulation of airamong the contact points 15, dust is accumulated which must be removed;By disengaging the latch members 27 and throwing back the clamping bars24, the two parts of the electrode 12 and the dielectric mav beliterally separated for the purpose of cleaning. r
